Abstract: Most enterprises are small- and medium-sized firms, but scholarship on corporate social responsibility (CSR) has focused on large corporations. In this paper, I study small, medium, and large firms' likelihood of engaging in a specific CSR activity—voluntary environmental information disclosure. I present evidence that in the oil and gas industry, large firms are more likely than small firms to voluntarily disclose to the general public information about the highly controversial industrial process of hydraulic fracturing.

Abstract: We look for evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes. The local certifications appear to have larger effects on sales prices, and that effect holds for both newer and older homes. The estimated home price premiums from certification imply annual energy cost savings that are sizeable fractions of estimated annual energy costs for homes in our sample, in some cases even above 100 percent. This suggests that the certifications either embody other attributes beyond energy efficiency that are of value to homebuyers or that buyers are overpaying for the energy savings. Further research is needed to better understand how consumers interpret home certifications and how they value the combination of “green” characteristics that many of those certifications embody.

Abstract: We evaluate the effectiveness of energy efficiency labeling in guiding household appliance choice decisions. Using a carefully designed choice experiment with several alternative labeling treatments, we disentangle the relative importance of different types of information and intertemporal behavior (i.e., discounting) in guiding energy efficiency behavior. We find that simple information on the economic value of saving energy was the most important element guiding more cost-efficient investments in appliance energy efficiency, with information on physical energy use and carbon dioxide emissions having additional but lesser importance. The degree to which the current EnergyGuide label guided cost-efficient decisions depends importantly on the discount rate assumed appropriate for the analysis. Using individual discount rates separately elicited in our study, we find that the current EnergyGuide label came very close to guiding cost-efficient decisions, on average. However, using a uniform five percent rate for discounting—which was much lower than the average individual elicited rate—the EnergyGuide label led to choices that result in a one-third undervaluation of energy efficiency. We find that labels that not only nudged people with dispassionate monetary or physical information, but also endorsed a model (with Energy Star) or gave a suggestive grade to a model (as with the EU-style label), had a substantial impact in encouraging the choice of appliances with higher energy efficiency. Our results reinforce the centrality of views on intertemporal choice and discounting, both in terms of understanding individual behavior and in guiding public policy decisions.

Abstract: There is little evidence from impact evaluation studies of ambitious residential energy conservation programs, especially in developing countries. In this paper, I investigate the short- and long-term impacts of the most ambitious electricity conservation program to date. This was an innovative program of private incentives and conservation appeals implemented by the Brazilian government in 2001-2002 in response to supply shortages of over 20%. I nd that the program reduced average electricity consumption per customer by 25% over a nine-month period in affected areas. Importantly, the program reduced consumption by 12% in the long run. Such persistent effects, which arose mostly from behavioral adjustments, may substantially improve the cost-effectiveness of ambitious conservation programs. Finally, I show that a price elasticity estimated out-of-crisis would have to be increased fivefold to rationalize conservation efforts by the private incentives alone. Appeals to social preferences likely amplify consumers' responsiveness in times of crisis.

Abstract: Tourism associated with beaches, protected areas, and other natural resources often has serious environmental impacts. The problem is especially acute in developing countries, where nature-based tourism is increasingly important and environmental regulation is typically weak. Eco-certification programs—voluntary initiatives certifying that tourism operators meet defined environmental standards—promise to help address this problem by creating a private-sector system of inducements, monitoring, and enforcement. But to do that, they must provide incentives for tourism operators to participate, such as price premiums and more customers. Rigorous evidence on such benefits is virtually nonexistent. To help fill this gap, we use detailed panel data to analyze the effects of the Blue Flag Program, a leading international eco-certification program, in Costa Rica, where nature-based tourism has caused significant environmental damage. We use new hotel investment to proxy for private benefits, and fixed effects and propensity score matching to control for self-selection bias. We find that past Blue Flag certification has a statistically and economically significant effect on new hotel investment, particularly in luxury hotels. Our results suggest that certification has spurred the construction of 12 to 19 additional hotels per year in our regression samples. These findings provide some of the first evidence that eco-certification can generate private benefits for tourism operators in developing countries and therefore has the potential to improve their environmental performance.

Abstract: Brownfields are properties for which redevelopment is hampered by known or suspected contamination and by concerns about associated liability. Because failing to redevelop brownfields may negatively affect welfare and the environment, a number of states have created voluntary programs to reduce liability risks and encourage redevelopment of brownfields. For clean or remediated properties, the state certifies that owners of such sites are not subject to federal or state liability under certain conditions. Certification could increase nearby property values because of decreased contamination risk and amenities associated with redeveloping the brownfield. This paper focuses on the Site Remediation Program in Illinois, and estimates the effect of brownfields certification on nearby property values. Employing several strategies to account for unobserved and time-varying variables that may be correlated with certification, I find that certification of a brownfield 0.25 miles away raises property values by about one percent. In aggregate, the program has increased nearby property values by about two percent.

Abstract: Over the past several years, labeling schemes that focus on a wide range of environmental and social metrics have proliferated. Although little empirical evidence has been generated with respect to carbon footprint labels, much can be learned from our experience with similar product labels. We first review the theory and evidence on the influence of product labeling on consumer and firm behavior. Next, we consider the role of governments and nongovernmental organizations, concluding that global, multistakeholder organizations have a critical part to play in setting protocols and standards. We argue that it is important to consider the entire life cycle of a product being labeled and develop an international standard for measurement and reporting. Finally, we examine the potential impact of carbon product labeling, discussing methodological and trade challenges and proposing a framework for choosing products best suited for labeling.

Abstract: According to proponents, voluntary agreements (VAs) negotiated with polluters sidestep weak institutions and other barriers to conventional environmental regulation in developing countries. Yet little is known about their effectiveness. We examine VAs in Colombia, a global leader in the use of these policies. We find that the main motive for using VAs has been to build capacity needed for broader environmental regulatory reform. Their additional effect on environmental performance has been questionable. These findings suggest that in developing countries, VAs may be best suited to capacity building, not environmental management per se.

Abstract: “Cash-for-Clunkers” was a $3 billion program that attempted to stimulate the U.S. economy and improve the environment by encouraging consumers to retire older vehicles and purchase more fuel-efficient new vehicles. We investigate the effects of this program on new vehicle sales and the environment. Using Canada as the control group in a difference-in-differences framework, we find that the program increased new vehicle sales by about 0.36 million during July and August of 2009, implying that approximately 45 percent of the spending went to consumers who would have purchased a new vehicle anyway. Our results suggest no gain in sales beyond 2009 and hence no meaningful stimulus to the economy. In addition, the program will reduce CO2 emissions by only 9 to 28.4 million tons, implying a cost per ton ranging from $91 to $288 even after accounting for reduced criteria pollutants.

Abstract: Commercial and residential buildings are responsible for 42 percent of all U.S. energy consumption and 41 percent of U.S. CO2 emissions. Engineering studies identify several investments in new enegy-efficiency equipment or building retrofits that would more than pay for themselves in terms of lower future energy costs, but homeowners and businesses generally do not have good information about how to take advantage of these opportunities. Energy auditors make up a growing industry of professionals who evaluate building energy use and provide this information to building owners. This paper reports the results of a survey of nearly 500 home energy auditors and contractors that Resources for the Future conducted in summer 2011. The survey asked about the characteristics of these businesses and the services they provide, the degree to which homeowners follow up on their recommendations, and the respondents’ opinions on barriers to home energy retrofits and the role for government. Findings from the survey suggest that the audit industry only partially is filling the information gap. Not enough homeowners know about or understand audits, and the follow-through on recommendations once they do have audits is incomplete. But the survey findings suggest that low energy prices and the high cost of retrofits may be more responsible for these outcomes than failures of information.

Abstract: Private sector initiatives certifying that producers of goods and services adhere to defined environmental process standards are increasingly popular worldwide. According to proponents, they can circumvent chronic barriers to effective public sector environmental regulation in developing countries. But eco-certification programs will have limited effects on producers’ environmental performance if, as one would expect, they select for those already meeting certification standards. Rigorous evaluations of the environmental effects of eco-certification in developing countries that control for selection bias are rare. The author used plant-level data on more than 80,000 Mexican facilities to determine whether ISO 14001 series certification of environmental management systems boosts regulatory compliance.

We use plant-level data on more than 80,000 Mexican facilities to determine whether ISO 14001 series certification of environmental management systems boosts regulatory compliance. We use propensity score matching to control for nonrandom selection into the program. We find that plants recently fined by environmental regulators were more likely to be certified, all other things equal, but that certified plants were subsequently fined just as often as similar uncertified plants. These results suggest that in Mexico, the ISO 14001 program attracts dirty plants under pressure from regulators—not just relatively clean ones—but does not have a large, lasting impact on their regulatory compliance.

Abstract: Interest in low emissions development is growing in many parts of the world for both climate and nonclimate reasons. Yet in order to pursue low emissions development, gaps in knowledge and implementation capacity must first be identified and and then filled through peer-to-peer learning and applied research. Governments, multilateral development banks, and nongovernmental organizations are responding to country-led efforts to implement low emissions development policies through an array of country-specific programs and projects. Most of these international programs operate independently, with collaboration among implementing agencies occurring on the margins at the national or local level. While these initial efforts are laudable and have yielded valuable knowledge and progress, the opportunity is ripe to leverage these activities for greater impact. Greater global cooperation through semiformal coordinating mechanisms could ensure greater coverage of low emissions development activities, enhance the scale and predictability of funds, and improve the ease with which countries engage in peer-to-peer exchanges. We propose that a new Consultative Group on Low Emissions Development (CGLED) could serve as this coordinating mechanism.

Abstract: Despite the recent popularity of conditional cash transfers (CCT) and payments for environmental services (PES) programs, what determines their success is not well understood. We developed a conceptual framework to give insight into some of the main determinants of CCT and PES program efficiency that hope to increase investments in human and environmental capital. We used a simple agent-based model and validated the results with empirical data from existing programs. We show that 1) the share of participants who meet the program’s conditions at baseline is a powerful predictor of program efficiency, (2) and selection bias erodes program efficiency to a large extent. (Selection bias stems from agents who already meet program criteria and who self-select into programs at higher rates than those who do not meet the conditions.) Based on these results, we discuss possibilities for improving efficiency—mainly by targeting applicants or increasing payments—and criteria for evaluating and choosing CCT, PES, or other policy instruments.

Abstract: This paper reviews the economic justification for voluntary environmental programs to derive defensible measures of their positive social outcomes. We consider ideal experimental and statistical designs to detect and attribute benefits. We also explore a set of more practical approaches to benefit attribution that take into account the data gaps and statistical challenges that often make more rigorous approaches infeasible.
